Phono stage.

Any more resistor questions, anyone? Or resistor measurement results. I have certainly been pleasantly surprised by the measured results.

i got resistors from Simon and they look very familiar to me. Quite big though.
I will listen, not measure if that is ok. I will use the latest version of my High Z MPP plus the Inductive RIAA. I have the resistors on Eichmann plugs so swapping is easy.
I will also get some Texas Components Naked Z Foils with the same values so a lot of work is before me. Sofar i got the best sound with 300 Ohm old military wirewound Dales. They sounded even better then the 1Kohm Naked Z Foil i have. The Z Foil where more detailed but the Dale had a more fleshed out sound i liked better.
They where not the same value though, so i will do that experiment again with the same values but different types.

Does anyone know of a QUALITY resistor like the naked Vishay, but significantly cheaper? I can't use naked Vishay's everywhere.

Let us see what Jocko has to say. The samples I sent him measure better and cost much less.

I expect there to be certain differences, but I will not say what they are so as not to influence his opinion.

I am using Vishay MBB 0207 resistors now, as a rule.

Joachim Gerhard · 8th April 2010, 10:46 PM

Here is latest information fron Vishay. Quite compete.
Listening to all this may need 10 years at last and i thought that i am a freak.
The real freaks are at Vishay.
I like the oil filled zerro temkcos just by looking at them.

Thanks, both of you.

Well, I guess we should try to go forward. I am glad that several of you have learned more about resistors than you previously thought measurable or possible. Why it should matter is something that we can only guess at. I hope that we can find something else to discuss that will not create too much concern or confusion.
